Methods. Within-group: paired t-test on Post − Baseline DBP, with 95% CI for mean change and Cohen's dz.
Between-group: Welch's t-test on changes, with 95% CI for the mean difference and Hedges' g.
Baseline-adjusted: OLS regression Post ~ Baseline + Group (ANCOVA-style).
KPIs and charts respond to filters; the stats panel always reflects the full sample.
Pre → post DBP, paired
Each line is one subject. Slope shows the change from baseline to post.
Hypothesis tests
Full sample, regardless of filters.
Distribution of DBP change by group
Histogram of (Post − Baseline). Negative = blood pressure dropped.
Subgroup forest plot — DBP change [95% CI]
Mean change in mmHg with 95% CI by group × sex.
